METAL SIDEWALK FORM.

Application filed August 24, 1925. Serial No. 52,024.

My invention relates to knockdown forms as used in the process of makingconcrete 'sidewalks and other concrete structures and has for its objectto provide a structure which will be light in construction and yetdurable, sectional and finally portable.

A further object of the invention is to construct a form which will becomposed of the. least number of parts possible and at the same timeconstructed so asto leave the device free from any loose parts whichcould become easily lost.

A further object of the invention is to construct the device out ofsheet metal of the tubular type and by arranging the parts in. suchmanner that an increase in speed with respect to the assembling anddismantlingof the form is produced.

With the objects above indicated and other objects hereinafterexplained, my invention consists in the construction and combination ofelements described and claimed. 1

Referring to the drawings:

In the drawings 1 and 2 indicate the longitudinal extending side piecesformed of a single piece of sheet. metal bent to shape and welded on theunder side as at 2} and i. In the shaping of the side pieces it isimportant that the inner faces and (S of the longitudinal side pieces bepositioned at right angles tov the surface to be concrete-d and it isfurther desirable to make the lower face 7 and 8 of sutiicient width toinsure asol-id .the. outer also within the recesses It and to be extendvtions, plates 19 and by means of rivets or setting or footing. It isfurther desired to construct the side pieces so that theouter sides 9and 10 are battered or sloping. This construction affords a very durableand strong form to tubular structure. In order to more lighten the formsections 11 have been cut into the under side thereof.

In the upper sides 12 and 13 of the longitndinal side pieces and spacedsuitably apart are cut recesses 14 which extend substantiall vdownwardinto both the outer and inner sides of the side pieces. Intothese recesses are placed division plates 15, the outer ends of whichare cut to fit snugly into the recesses 14. As a means for preventingthe displacement of these divisional plates 15, pivotal T shaped handles16 are secured to ends thereof and adapted to lit ed into horizontalposition resting upon the outer side 10 and locking said division platethoroughly in place.

In order to assemble a number of these forms together an angle 17 issecured to the battered side of. the side pieces and substantially atone end thereof. At the opposite end and on the same side and center, aZ, shaped member 18 the center and adapted to extend, when in horizontalposition, over an angle similar to 17, secured to the section to besecured thereto. As a means of aligning the several sec- 20 are rigidlyfastened to the inside of the longitudinal side pieces bolts 21, aportion of said plate. extending forwardly a sufiicient distance toenter the adjoining section. The use of the two plates holds thesesections in line and by clamping the 2 member 18 over the ing As afurther means a channel member 22 being the same as the distance betweenthe inside of the longitudinal side pieces. To this channel 22 isriveted or bolted a piece of flat iron 23 for the entire length thereof.Upon the top surface of the channel 22 and at the outer ends thereof areprovided handles 24 which serve as a means for lifting this member. Theparticular feature of this member is its bracing and reinforcingquality. After the division plates 15 are in position-and locked thechannel 22 is laced over the said division plate'15', the at iron -23resting against the side thereof and the ends separated or disengaged.

of bracingthe .fopqrof is provided, pivoted in angle 17 they areprevented from becom-- is providedfits widtli" .ing the plates securely;,After .slots ltand the T-shaped. handles 16 extended into horizontalposition thereby lockthe several plates have been secured in positionthe .channel iron 22-is then placed these several plates. The Width ofthe channel 22 being of substantially the same width asthe distancebetween tie inside of the 17 thereby longitudinal side it beingnecessary nels into place.

'Now if it is these forms together each section of the form may be builtup separately and then joined together by placing the ends containingthe plates'18 and 19 inside of the end of the adjoining sectioncontaining the angle maintaining these sections in alignment. To securethese sections against becoming disengaged or separated it is merelynecessar Y to rotate the 2 member 18 until the end thereof extends overand enpieces, insures a snug-flit, to lightly force these changages theupstanding leg of the angle -17.

It will be readily seen from the foregoing description that my device isfree from all individual or separate pieces which is neces sary tomostof the forms now used. The chances of losing any of the parts is therebyobviated and the construction simplified.

Having thus described my invention What I claim is 1. In a form forconcrete sidewalkspthe combination of longitudinally extending side asingle sheet of members formed from metal, having their outer facesinclined outward and downward, recesses provided in the over each ofsecured desired to secure several of upper surface of said side membersand 8X- tending downwardly a substantial distance into the sideportions, partition plates adapted to reside Within said recesses andmeans carried by the partition plates for locking said partition plates,in the recesses adapted to engage the inclined outer faces of the sidemembers.

2. In a form for concrete sidewalks, the combination of longitudinallyextending side members, tubular in cross section, formed from a singlesheet of metal, recesses provided in the upper surface of said sidemembers and extending downwardly a suhstarr tial distance into the sideportions, partition plates having their ends adapted to reside Withinthe recesses and a pivoted member to the outer end of said partitionplates adapted to be extended into horizontal position through saidrecesses and to lock the partition plates against displacement.

3. In a form for concrete sidewalks, the combination of longitudinallyextending side members, tubular in cross section, formed from a singlesheet'of metal, recesses provided in the upper surface of said side members, and extending downwardly a suhstantial distance into the sideportions, partition plates having their ends adapted to reside withinthe recesses, a pivoted member cured to the outer end of said partitionplates adapted to be extended into horizontel position through saidrecesses and to lock the partition plates against displacement, a platesecured to one end of said tubular member and adapted to engage the endof an adjoining tubular member toretain said members in alignment and arotatable member secured at one end of the tubular side member andhaving a depending portion adapted to engage the upstanding leg of anangle secured to the adjoining side member, to prevent separationthereof.
